Bronx scientists have completed a quest to hear the piercing shriek of a cuckoo.

The cuckoo in question is actually a rare Sumatran bird, believed to be extinct until a decade ago.

A team of biologists from the Bronx Zoo-based Wildlife Conservation Society found one on the Indonesian island of Sumatra and recorded its call for the very first time.

The call is a very loud, two-syllable shriek that apparently sounds nothing like a Bronx cheer.

American Airlines is investigating.

That’s more than $100,000 below its assessed value.

Michael Sparks, a music-equipment technician, will auction off the document on March 22. The starting bid is $125,000.

A love caravan of about 150 women descended on a small Spanish town after the village’s male farmers put out an Internet call for companionship.

The women arriving in Hoyocasero – a town of 400 about 60 miles west of Madrid – were greeted by men bearing flowers.

“Meeting someone this way, it’s more rustic and more authentic,” said one of the farmers. “It’s easier to get to know someone face to face.”
